    vect: Don't apply masks to operations on invariants [PR108979]

    The loop body in the testcase contains an operation on invariants.
    SLP detects this and can hoist/schedule the operation outside of
    the loop.  However, after the fix for PR96373, we would try to
    apply a loop mask to this operation, even though the mask is
    defined in the loop.

    The patch does what Richi suggested in the PR: suppress the
    masking for externs and constants.

            operations on invariants.
